Special note about Heart Lake The traditional trail to Heart Lake and Little Castle Lake leaves the east end of the parking area and ascends to the divide above the east side of the lake. It begins on public land in section 24 of T39N R5W but immediately crosses the boundary of section 19 of T39N R4W. This entire section of land (about 640 acres) is privately owned property and posted as such. There is no legal access across this section to these lakes. Please be respectful and avoid…
